Verified step by step guidance

Understand the structure and function of nucleic acids: Nucleic acids, such as DNA and RNA, are macromolecules responsible for storing and transmitting genetic information. Their structure is composed of repeating monomer units.

Identify the term 'monomer': A monomer is a single, basic unit that can join with other similar units to form a polymer. In the case of nucleic acids, the polymer is DNA or RNA.

Examine the options provided: Fatty acids are components of lipids, amino acids are monomers of proteins, and monosaccharides are monomers of carbohydrates. None of these are directly related to nucleic acids.

Define the correct monomer: Nucleotides are the monomer units of nucleic acids. Each nucleotide consists of three components: a phosphate group, a pentose sugar (either ribose or deoxyribose), and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil).

Conclude the reasoning: Based on the structure and function of nucleic acids, the correct answer is 'Nucleotide,' as it is the building block of DNA and RNA.
